Topic overview

This chapter covers the physical and mechanical basics that make driving safe: your own fitness to drive (vision, hearing, alertness, medication effects), the correct hand positions for steering, and when and how to signal, honk, and use your headlights.

The most-tested ideas are the specific rules around signaling (well before a turn or lane change, even when no one else seems to be around) and headlight use (turning them on whenever visibility drops — not just at night, but in bad weather, on mountain roads, and in tunnels — plus dimming your high beams for oncoming and same-direction traffic). Fatigue and impairment are treated as safety hazards just like poor vision, since both slow your reaction time.

A common mistake is thinking signaling or headlights are just courtesy — they're legal requirements with specific timing. Another is not knowing the difference between the steering methods: hand-to-hand for normal driving versus hand-over-hand for low-speed turns, parking, or skid recovery. Also remember it's illegal to drive wearing a headset or earplugs in both ears — hearing is treated as essential as seeing.

When am I supposed to turn on my headlights?

Whenever visibility is reduced — not just after dark, but also in rain, fog, on mountain roads, or in tunnels — and you must dim your high beams for other traffic.

Does fatigue really count as a driving hazard?

Yes — the handbook treats fatigue and drowsiness the same way it treats poor vision: both slow your reactions and are a real safety risk.
